Well to kinda explain it as clear as mud....... As the engine revs up, the turbo builds boost pressure in the intake manafold which has a small line attached to it which goes to the ALDA on the injection pump. As the ALDA gets boost, It inturn gives the injectors more fuel which inturn creates more exhaust pressure which turns the turbo faster which inturn creates more intake manafold pressure............get the idea??? You are feeling the engine get into its "SWEET SPOT". You can help things along by turning the sealed screw on the alda a 1/2 to 1 turn counterclockwise. This gives you more fuel at zero to low boost. The car will pull out better and thus you will have to throttle it less to get going...... Clear as mud!!!
